[0032] Chip conveyors are common equipment on machine tools, used to collect iron chips, copper chips or other fine chips generated during machine tool processing. Chip conveyors include spiral chip conveyors, scraper chip conveyors and magnetic chip conveyors, among which the magnetic chip conveyors are used to collect iron chips through magnetic bodies. The magnetic chip conveyors mainly include a frame, the frame is provided with a collection plate, the collection plate generally extends along the length direction of the frame, one end of the collection plate in the length direction is the discharge end, a collection box is provided at the discharge end of the collection plate, and the frame is provided with a transmission chain below the collection plate, the transmission chain is provided with multiple magnetic bodies, and the transmission chain is used to drive the magnetic body to move along the length direction of the collection plate. When the iron chips fall onto the collection plate, the transmission chain drives the magnetic body to move, and the magnetic body can drive the iron chips to move to the collection box at the discharge end of the collection plate through magnetic force, thereby realizing the collection of iron chips.

[0033] However, during use, it was found that since the magnetic body is very close to the collecting plate, and some of the iron filings produced by processing are heavy and have a high temperature, when they fall onto the collecting plate, the collecting plate is prone to bend downward and deform, and the deformed collecting plate is prone to touch the magnetic body and damage it. In addition, when the transmission chain drives the magnetic body to move, the collecting plate is also prone to interfere with the magnetic body and destroy it.

[0034] Reference below Figures 1 to 5 A chip removal device for a machine tool according to an embodiment of the utility model is described.

[0035] like Figures 1 to 5 As shown, the chip removal device for a machine tool according to an embodiment of the utility model includes a frame 100 , a transmission chain 200 and a plurality of mounting frames 300 .

[0036] For example, the frame 100 may include a first horizontal section, an inclined section and a second horizontal section, the second horizontal section may be higher than the first horizontal section, the inclined section is located between the first horizontal section and the second horizontal section, the frame 100 is provided with a collecting plate 101, the collecting plate 101 extends along the length direction of the frame 100, the collecting plate 101 located on the first horizontal section is used to receive fallen iron filings, the end of the collecting plate 101 located on the second horizontal section may be a discharging end, and a collecting box may be placed below the discharging end.

[0037] A plurality of transmission gears may be provided on the frame 100, a transmission chain 200 may be installed between the plurality of transmission gears, the transmission chain 200 may be located below the collecting plate 101, the transmission chain 200 may extend along the length direction of the frame 100, the transmission chain 200 may include a conveying section 201 close to the collecting plate 101 and a return section 202 located below the conveying section 201, at least one transmission gear may be connected to a driving motor, and when the driving motor is started, the driving motor may drive the transmission gear to rotate, thereby driving the transmission chain 200 to move.

[0038] A plurality of mounting frames 300 are provided on the transmission chain 200 and can be arranged at intervals along the length direction of the transmission chain 200 , and the mounting frames 300 are provided with a magnetic body 301 and a protective portion 302 , wherein the top end of the protective portion 302 on the conveying section 201 is higher than the top end of the magnetic body 301 on the conveying section 201 , and correspondingly, the bottom end of the protective portion 302 on the return section 202 is lower than the bottom end of the magnetic body 301 on the return section 202 .

[0039] In the present invention, one end of the collecting plate 101 in the length direction can be the discharging end, and the transmission chain 200 drives the magnetic body 301 on the mounting frame 300 to move along the length direction of the frame 100, that is, to move along the length direction of the collecting plate 101. When the iron filings fall onto the collecting plate 101, the magnetic body 301 can drive the iron filings to move to the discharging end of the collecting plate 101 through its own magnetic force, thereby realizing the collection of the iron filings. According to the chip removal device for machine tools of the present invention, since the mounting frame 300 is also provided with a protective part 302, and the top of the protective part 302 located on the conveying section 201 is higher than the top of the magnetic body 301 located on the conveying section 201, when the collecting plate 101 bends and deforms downward, it will first abut against the top of the protective part 302. With the support of the protective part 302, the collecting plate 101 cannot continue to bend and deform downward, so that it will not touch the magnetic body 301 and damage the magnetic body 301, and the practicality is better.

[0040] It should be noted that, with the support of the protection part 302, the collecting plate 101 cannot continue to bend and deform downward, thereby preventing the collecting plate 101 from directly damaging the magnetic body 301, and preventing the collecting plate 101 from interfering with the movement of the magnetic body 301 and damaging the magnetic body 301 when the transmission chain 200 drives the magnetic body 301 to move. The magnetic body 301 can be a permanent magnet or an electromagnet.

[0041] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the mounting frame 300 includes a mounting plate 303, and a mounting groove 304 is provided at the top of the mounting plate 303, and the magnetic body 301 is fitted into the mounting groove 304. When the magnetic body 301 needs to be installed, the magnetic body 301 is fitted into the mounting groove 304. When the magnetic body 301 needs to be cleaned, repaired or replaced and the magnetic body 301 needs to be disassembled, the magnetic body 301 is moved upward so that the magnetic body 301 can be taken out from the top of the mounting groove 304, and the magnetic body 301 can be easily disassembled. In addition, the bottom surface and the inner side wall of the mounting groove 304 abut against the magnetic body 301, so that the magnetic body 301 is installed more stably, and the mounting structure strength is higher. When moving with the transmission chain 200, it is less likely to fall off, deform or be damaged, and it will not move randomly relative to the transmission chain 200, thereby driving the iron filings to move better.

[0042] In some embodiments of the present invention, Figure 4 As shown, the mounting groove 304 extends to both sides of the rack 100 along the width direction of the rack 100, and the magnetic body 301 is configured as a strip structure and extends to both ends of the length direction of the mounting groove 304. For example, the mounting plate 303 can extend to both sides of the rack 100 along the width direction of the rack 100, and the mounting groove 304 can extend to both ends of the mounting plate 303 along the length direction of the mounting plate 303. Such a configuration makes the magnetic attraction of the magnetic body 301 more comprehensive and extensive, thereby driving the iron filings to move better, thereby achieving a better effect of collecting the iron filings.

[0043] In some embodiments of the present invention, Figure 3 As shown, the protection part 302 is detachably connected to the mounting plate 303, and the bottom end of the protection part 302 abuts against the top end of the magnetic body 301. In this embodiment, in addition to abutting against the bottom end of the collecting plate 101 when the collecting plate 101 is deformed downward to prevent the collecting plate 101 from further deforming downward, the bottom end of the protection part 302 also abuts against the top end of the magnetic body 301, thereby positioning the magnetic body 301 and preventing the magnetic body 301 from being randomly moved out of the top end of the mounting groove 304, thereby making the installation of the magnetic body 301 more stable, and the protection part 302 is dual-purpose in one piece, and has better practicality.

[0044] In some embodiments of the present invention, Figure 3 and Figure 5 As shown, the protection part 302 includes a connecting section 305 and an abutting section 306, the connecting section 305 is connected to the mounting plate 303 by a fastener, and the bottom end of the abutting section 306 abuts against the top end of the magnetic body 301. For example, the mounting plate 303 can be provided with a plurality of first mounting holes along the length direction, and the connecting section 305 of the protection part 302 can be provided with a plurality of second connecting holes along the length direction, the first mounting holes correspond to the second connecting holes one by one, the first mounting holes are aligned with the corresponding second connecting holes, and the fasteners are installed between the first mounting holes and the second connecting holes to realize the installation of the protection part 302, which has a simple structure and is easy to install, and the abutting section 306 can abut against the magnetic body 301 to facilitate the positioning of the magnetic body 301.

[0045] It should be noted that the protection portion 302 may also be snap-connected to the mounting plate 303, which will not be described in detail herein.

[0046] In some embodiments of the present invention, Figure 3 As shown, there is a gap between the top surface of the abutting section 306 and the bottom surface of the collecting plate 101. In this embodiment, when the collecting plate 101 is not bent and deformed downward, there is a gap between the top surface of the abutting section 306 and the bottom surface of the collecting plate 101, and thus when the collecting plate 101 is not bent and deformed downward, the collecting plate 101 can be prevented from contacting the abutting section 306 of the protective part 302, thereby not only preventing the abrasion of the abutting section 306 between the collecting plate 101 and the protective part 302, but also preventing the collecting plate 101 from interfering with the movement of the protective part 302, and having better practicality.

[0047] In some embodiments of the present invention, Figure 3 and Figure 5 As shown, the top surface of the abutment section 306 is set to be an arc surface convex upward. In this embodiment, such a setting, even if the collection plate 101 is bent and deformed downward to abut the top surface of the abutment section 306, and the transmission chain 200 drives the mounting frame 300 to move, and then drives the abutment section 306 of the protection part 302 to move, the friction between the collection plate 101 and the abutment section 306 of the protection part 302 is also small, thereby not only making the abrasion of the collection plate 101 and the abutment section 306 of the protection part 302 small, but also the interference caused by the collection plate 101 on the movement of the protection part 302 is small, and the practicality is better.

[0048] In some embodiments of the present invention, Figure 3As shown, two protective parts 302 are provided, and the bottom ends of the two protective parts 302 respectively abut against the top ends of the two sides of the width direction of the magnetic body 301. For example, the two protective parts 302 are respectively located on the two sides of the width direction of the magnetic body 301, and the bottom ends of the two protective parts 302 respectively abut against the top ends of the two sides of the magnetic body 301. In this embodiment, such a configuration makes the protective parts 302 have a better limiting effect on the magnetic body 301, so that the magnetic body 301 is installed more stably.

[0049] In some embodiments of the present invention, Figure 5 As shown, the protection part 302 extends to both sides of the frame 100 along the width direction of the frame 100. With such a configuration, when the collecting plate 101 is bent and deformed downward at any position in the width direction, the protection part 302 can abut against the bottom end of the collecting plate 101, thereby preventing the collecting plate 101 from continuing to bend and deform downward at any position in the width direction and touching the magnetic body 301, thereby providing a better protection effect on the magnetic body 301, and the magnetic body 301 is less likely to be damaged. In addition, the protection part 302 has a better limiting effect on the magnetic body 301, thereby making the installation of the magnetic body 301 more stable.

[0050] In some embodiments of the present invention, Figure 3 As shown, the transmission chain 200 includes a plurality of chain units 203, two adjacent chain units 203 are hinged through a hinge shaft 204, two hinge shafts 204 of some chain units 203 have extension sections, and the mounting frame 300 also includes a connecting plate 307, the connecting plate 307 is provided with a sleeve hole 308 and is sleeved on the extension section through the sleeve hole 308. For example, the connecting plate 307 may be provided with two sleeve holes 308, the two sleeve holes 308 are respectively sleeved on the extension sections of two hinge shafts 204 of the same chain unit 203, and the extension section is threadedly connected with a locking nut 205 on the side of the connecting plate 307 away from the chain unit 203. In this embodiment, the mounting frame 300 is installed on the hinge shaft 204 of the chain unit 203 through the connecting plate 307, which is not only simpler in structure, but also more convenient to install. In addition, when the transmission chain 200 moves around the transmission gear, the interference between the mounting frame 300 and the transmission chain 200 can be reduced, so that the transmission chain 200 moves more smoothly and avoids jamming.

[0051] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
